Abstract:
    1. Technology fields: 1.1 the technology of network wireless microwave digital data transmission of mobile communication as well as measuring time and distance. 1. 2 conducting wire measure technology of geodesy. 2. Technical problems and the main points to solve: 2.1 Distance measurement measures by the distance detection documentation, Mobile communication networks through fixed the begin and end time of the binary digital measure transmission documents which is send between the base stations and cell phone back and forth between transmit measured, multiply the speed to obtain the exact distance between them. It is used to measure the distance between the fixed station which send and receive digital information by microwave and the mobile station with the same feature. 2.2 the compendia and precise orientation of the cell phone is located using the three side which has calculated the length between the base station which has measured the three-dimensional coordinate by mobile communication network and the cell phone as well as the altitude difference between each based station and the cell phone, calculates the triangle which is composed of three level distance side, using triangular corner and the conducting wire measurement formula to obtain the location of the three-dimensional coordinate of the mobile station. Use 1) measure 3-D coordinates of the points. 2) Cell phone coordinate with an electronic map to locate for transport and individual.
